Aidan O'Brien has confirmed that Saxon Warrior is to be retired after damaging a tendon in Saturday's Irish Champion Stakes at Leopardstown. 

The three-year-old, heralded as one of the finest colts of his generation last year and a winner of the Beresford Stakes and the 2000 Guineas in Newmarket, was edged out by Roaring Lion in a tight finish in yesterday's Qipco Irish Champion Stakes. 

Post-race, it was discovered that he had badly damaged his tendon and the decision has been taken to retire the horse. 

"He badly damaged his tendon in the race," O'Brien told RTÉ Racing.

"He came home last night and was a little bit sore. So, we wrapped him up. When we took the wraps off him this morning, his tendon wasn't in a good place. There was a significant tear in the core tendon. 

"It's a big pity. He was an amazing horse, really. Coming in this year, I thought he was a horse that had a chance of winning the Triple Crown.

"When we won the Guineas. We wanted to give him a chance of the (Epsom) Derby. I felt he didn't handle the track. 

"An amazing horse. Listen, it's a pity but we were delighted to have him and we're looking forward to his foals."
